Like a lot of other four-layer semiconductors, thyristors have a "body diode" or "parasitic diode" formed by the way the structure sits on the intrinsic silicon substrate.

Spending time in a room with an uncovered UV-light will cause blindness and skin cancer in the long run.

I think that thyristor thing is pretty much a standard trick. I haven't used thyristors, but I've used Triacs which are pretty much the same thing. Triacs can be fired in FOUR different quadrants, and I'm pretty sure this is just the other one of those quadrants that will fire it.

[@SeanBZA]

Triac will fire in all 4 quadrants because it is bidirectional. Thyristor is only going to fire in quadrant one, and will only fire with both positive gate voltage and positive anode, and resemble a diode in all other quadrants and stay off. Running the gate into reverse breakdown will however cause damage to the thyristor itself, as the gate area is small, and will degrade from running in reverse breakdown, as it is a reverse biased emitter base junction. Small thyristors are not rated for use with gate turn off, where you deliberately use reverse bias on the gate to starve the thyristor latching, to turn it off. You do need a different design to get the gain of the lower transistor high enough so the gate current, which will be almost the load current at it's peak, which you pull out to turn off, is enough to turn the transistor off. The gate path needs to be large enough to handle this current, and in a small device, where it only has to handle 50mA or so of drive to start it turning on, the junctions will rapidly degrade. Long term this thyristor will simply fail as short circuit gate to cathode, and stop functioning, though it probably will take a year or so to do that if use cycle is low, but only a few thousand mains cycles will degrade it. Another diode added to allow the current flow would have prevented that.

I stumbled across this video and really liked it. More, I think of buying one of those gadgets. Since now I have had an instructional like I never had before! Very cool! And well explained! After a second or two of research I now know what it is for. It is for getting chopsticks sterile. Must have been made to be installed in a drawer or so.

Not sure, since it seems to fire on the other half of the sinewave it charged on, and is effectively a closed loop with a decent core. Not sure about the corona noise.

[@carpdog42]

I must point out that this video is evidence of an error in Wikipedia's page on Thyristors which clearly states "Thyristors have three states: .. reverse blocking... forward blocking... forward conducting". We know have demonstrated proof that "Reverse gate breakdown" is actually a 4th mode with a demonstrated application.

[@Aco747lyte]

My sister reckons the device is a small ozone generator for putting in a small cupboard to sterilize equally small items. Suitably enclosed, the generator would be a lot more effective. Seeing that corona sparking off with the light out made her think this was the only solution, probably being even more effective if placed in a plastic bag, sealed off to maximise the ozone effectiveness. Many thanks Clive. This was most interesting!

[@bigclivedotcom]

Hey Clive, 240 is only about 10% above 220 so we should only see ~13.2V across the relay. I'm guessing the capacitor passes 60Hz better than 50Hz as well.

[@stargazer7644]

3902 ohms at 60 hz vs 4683 ohms at 50 hz.

[@paulcozz1]

Long time watcher,its rare I comment. A Question you could Answer?.. does Ozone like dry air ? I have recently implemented ozonated water in the laundry business I own, using an ozone injection unit that mixes the ozone with the water. It uses a desiccant cartridge to dry the incoming air, so does a 'normal' ozone generator perform better with dry air ?

[@bigclivedotcom]

I think it does improve the conversation of oxygen to ozone.

That sort of highly elastic silicone-like material is used on automotive circuit boards, to protect components against vibration and corrosion. I recently took apart an electronic throttle module from a 1999 Volvo, and the circuit board, and the gooey stuff on it, was 100% like new. The stuff does not age at all.

[@misterhat5823]

Odd use of the thyristor. I'd feel much better with a 1N4148 from gate to cathode. Allowing breakdown to occur normally shortens the life of a semiconductor.

[@sitechca70]

No expert here but zener diodes do operate continuously in the breakdown region. There is nothing special in their manufacturing to allow that other than to tune the breakdown voltage.

[@misterhat5823]

@@sitechca70 Exceed the reverse breakdown voltage for the base emitter junction of a transistor and allow it to breakdown. See how long it meets specifications.

[@karenfay4545]

The potting may be parylene coating. Thyristors are sometimes referred to as SCRs. The relay is LVP (low voltage protect) which must be reset when it drops out. They are using the inductive and capacitive KICK of the collapse of the B field in the inductor reinforced by the E field capacitor discharge current to power the lamp as a weird flash lamp or and odd sorts of line high frequency relaxation oscillator.

I work at a plastic injection molding company where one of our container printing presses, we make containers and lids for the food industry, the press used a very powerful corona generator instead of a flamer to pretreat the plastic to insure that the ink stays stuck to the plastic before rotating in front of the 3000 watt UV light to cure the ink. If you looked inside the press while it's running and observing the corona position on the indexer it's a big purple lightning show, probably several thousand times stronger than this device. But still a really cool explanation and sight to see! Thanks!

[@bigclivedotcom]

I've come across the plasma treatment of plastic for printing. Including an unfortunate incident when the operator got over familiar with it and was electrocuted as a result.

[@donaldgregg9250]

@@bigclivedotcom The metal bars of which emits the plasma arc is only energized when the press is running. I could see if a person became too complacent, brave and ignorant enough to possibly reach through an opening such as the sturdy flexible rubber shield that is a pivot point for allowing the gap for direct pressure and toe, to possibly tap the bars with a long enough metal object while the press is running to adjust the distance or angle of the bars for better pretreatment they could be electrocuted. The housing for the electronics that generates the high voltage for those bars is on the top of the press. It consists of a large transformer and other components to regulate the charge. If that is tampered with during operation of the press, to possibly make adjustments there in place of any use of the variable adjustments that are mounted to that housing could also cause electrocution. The two wire leads that travel from that box are shielded with conduit, if either of these, the leads or conduit are damaged or modified or compromised could also cause a safety risk. Thanks for your comment and good to know others here are familiar with this type of equipment
